I'll post some glaze tests. Here is how they were fired:
150=BAF/hr to 2100
50=BA/hr to 2160 (cone 6 half-way down)
Hold for 15 minutes
Cool naturally to 1900=BA
Cool at 100=BA/hr to 1500=BA
Cool naturally to room temperature (12=BA below zero in this particular
case--brrrr! Actually, I only let the pots get down to 60=BA. They felt n=
ice and
warm.)
I fired so slowly because I had a large piece with a minor glaze flaw to =
re-fire
and I didn't want it to blow up. Normally I would have fired at 200=BAF/h=
r in the
first phase, which is also pretty slow, but that's how I'm doing it at th=
e
moment.
All pieces were brown stoneware clay with grog.
